The condition develops when nerve cells that are responsible for producing a chemical known as dopamine die.
Dopamine allows messages to be sent to the parts of the brain that coordinate movement. With the loss of dopamine-producing nerve cells, these parts of the brain are unable to work normally, causing symptoms of Parkinson’s to appear.
There are more than 40 symptoms but Parkinson’s affects everyone differently. Not everyone will experience all the symptoms.
Parkinson’s doesn’t directly cause people to die, but symptoms do get worse over time.
